feat(query-core): make `MutateFunction` optional undefinable-variables

[unnoq]

Old Behavior:
.mutate, .mutateAsync, ... allowed omitting the variables parameter only when its type was exactly void.

However, in TypeScript, when using union types like unknown | void, the void portion is ignored and treated as unknown, which still requires that variables be provided.

New Behavior:
.mutate, .mutateAsync, ... now allow omitting the variables parameter when its type can be undefined.

This change significantly broadens the optional types, supporting cases such as unknown, any, undefined | ..., void | ..., ...

Another benefit of the new approach is that, for popular schema libraries like Zod and Valibot, it is easier to define an undefinable schema than a void-able one.
